Visportal Tips

Recommended Posts

It's my understanding that a visportal will not work if a model bisects it. If I put a visportal in the middle of a sealed hallway, but the trim on the wall is a model that spans the length of the hall, the visportal will not work, both for rendering AND sound. Is this correct?

 

If it is, how does one put a visportal in a doorway if you're using a doorframe model? The visportal can't extend into the doorframe model unless my assumption above is incorrect. But models can't seal an area, so the visportal can't just stop at the doorframe. Or do you have to do something like make a caulk brush that is flush with the side of the doorframe model (I assume caulk dosn't create z-fighting?)?

 

Also, where do you put the portal in relation to the door, if the door is a model?

The visportal won't stop working altogether, it just won't occlude the particular model which bisects it. In your example the trim would not be affected by the visportal, but the hallway geometry and any other models which were inside it would be culled normally.

      I've finally managed to log in to The Dark Mod Wiki. I'm back in the saddle and before the holidays start in full, I'll be adding a few new FM articles and doing other updates. Written in Stone is already done.

      You cannot receive PMs. Could you please be so kind and check your mailbox if it is full (or maybe you switched off the function)?

      I like the new frob highlight but it would nice if it was less "flickery" while moving over objects (especially barred metal doors).
